Cryptography

Because it can! — In cryptography (if you are interested in the subject I highly recommend you follow Prof Bill Buchanan OBE) we use random numbers all the time. As you probably know, we need strong number generators with good sources of entropy to generate high quality random numbers. Would you say that 121212121212…

I have been writing about the Ring cryptography library for a while now and so in this post I am sharing a resource which I think will be a useful reference for developers implementing applications or protocols using the library. This is basically a cheatsheet of example code showing how…

Naive approach to Big Primes Numbers — Primes, primes, primes… these rare numbers are something between funny and slippery; so interesting and ridiculous difficult to find! You know that prime numbers have been something that cautivated almost any matematician since the acient greek days. And still do!! It’s been proven by Euclid in the acient greek times…

While working on a recent project, I found myself knee-deep in the mechanics of the Diffie-Hellman protocol, as its role in enabling secure, encrypted communications was integral to the project and its importance couldn’t be overstated. This wasn’t my first encounter with the protocol, but it was the first time…

The Enigma Machine is a true icon in the world of cryptography, captivating generations of mathematicians and computer scientists. Developed by the Germans during World War II, even the experts considered this machine impregnable until the ingenious efforts of Alan Turing and his team at Bletchley Park. …

In a world that’s rapidly embracing digitisation, two technologies have emerged as front-runners in revolutionising the landscape: Quantum Computing and Bitcoin. Each in their respective domains have set the stage for transformational changes that could redefine how we perceive computation and finance. …

One of the most disturbing vulnerabilities in EmbeddedSystems is the MeltdownSpectre attack. The main risk is that it affects most modern chips, allowing any program to read data without permission. This is due to an optimization feature in modern processors called speculative execution. …

Introduction The rapid rise of cryptocurrencies has disrupted various industries, and gaming is no exception. In recent years, the integration of cryptocurrencies, such as Bitcoin, Ethereum, and others, into the gaming world has garnered significant attention. The advent of blockchain technology and decentralized finance (DeFi) has opened up exciting possibilities…
